       Process that has priority above WIN32_NORMAL_PRIORITY_CLASS but below

       Process that has priority above WIN32_IDLE_PRIORITY_CLASS but below
       WIN32_NORMAL_PRIORITY_CLASS.

     <tr id="constant.win32-high-priority-class">
      <td><strong><code>WIN32_HIGH_PRIORITY_CLASS</code></strong></td>
      <td>0x00000080</td>
      <td>
       Process that performs time-critical tasks that must be executed
       immediately. The threads of the process preempt the threads of normal or
       idle priority class processes. An example is the Task List, which must
       respond quickly when called by the user, regardless of the load on the
       operating system. Use extreme care when using the high-priority class,
       because a high-priority class application can use nearly all available
       CPU time.
      </td>
     </tr>

     <tr id="constant.win32-idle-priority-class">
      <td><strong><code>WIN32_IDLE_PRIORITY_CLASS</code></strong></td>
      <td>0x00000040</td>
      <td>
       Process whose threads run only when the system is idle. The threads of the
       process are preempted by the threads of any process running in a higher
       priority class. An example is a screen saver. The idle-priority class is
       inherited by child processes.
      </td>

     <tr id="constant.win32-normal-priority-class">
      <td><strong><code>WIN32_NORMAL_PRIORITY_CLASS</code></strong></td>
      <td>0x00000020</td>
      <td>
       Process with no special scheduling needs.
      </td>
     </tr>

     <tr id="constant.win32-realtime-priority-class">
      <td><strong><code>WIN32_REALTIME_PRIORITY_CLASS</code></strong></td>
      <td>0x00000100</td>
      <td>
       Process that has the highest possible priority. The threads of the
       process preempt the threads of all other processes, including operating
       system processes performing important tasks. For example, a real-time
       process that executes for more than a very brief interval can cause disk
       caches not to flush or cause the mouse to be unresponsive.
